Here's proof that growing up doesn't always means getting rid of your toys.
The Super Awesome Micro Project is the brain child of Melbourne-based entrepreneur Steve Sammartino and 20-year-old Romanian tech wunderkind Raul Oaida. The pair built a fully functioning car out of 500,000 Lego pieces with the help of 40 Australians who donated the needed funds based on a single tweet from Sammartino. While the wheels and some of the load bearing elements are not Legos, the entire engine is made from the little plastic blocks. The car is powered with highly compressed air.
The LEGO hotrod was built with four orbital engines that included 256 pistons. It can reach twenty miles and hour with two passengers, putting a whole new spin on the term "toy car."
